(01.122-264) I I Q 1 Claim.

My invention relates to improvements in water heating and distributionplants. v e l The invention is designed with the particular purpose inView of providing an efiicient, outdoor plant for heating water andconveying the same under pressure, and preferably under ground todiverse and remote points for underground release and at selectedlocations to saturate the ground in orchards, groves, nurseries, and thelike with heater water deposited in pools or not as desired asaprotection against frost and freezing.

Another object is to provide a. plant of the character and for thepurpose above set forth which is adapted for converting into an indoordomestic heating system.

Still another object is to provide improved oil burning equipmentforheating the water, the improvements in this respect being particularlydirected to proper carburation of the fuel oil and preheating the same.7

, Other objects, more or less subordinate in character, are alsocomprehended by my invention, all of which together with the precisenature of my improvement will be readily understood when the succeedingdescription and claim are read with reference to the drawings accomvpanying and forming part of this specification.

In said drawings, Figure 1 is a vView in perspective of a preferredembodiment of my invention.

Figure 2 is a fragmentary View in longitudinal vertical section takenthrough the boiler and appurtenant parts and drawn to an enlarged scale.

Figure 3 is a view in transverse section taken on the line 33 of Figure2 looking in the direction indicated by the arrows.

.Figure 4 is a view in vertical longitudinal section taken through thefuel tank.

Figure 5 is a View in longitudinal section taken reference to thedrawings by numerals, in the ably centered below the same.

preferred embodiment thereof, as shown in Fig"- ures 1 to 7, the plantof my invention comprises as a basic'unit a" boiler l including anelongated transversely arched shell 2 having straight sides 3 andinternal reinforcing angle bars 4 extend,- ing along'the bottom edgesthereof providing base supporting structure for the shell. The shell 2is closed at its ends by front and rear crown sheets 5 and 6 and a pairof circular drumlike front and rear outlet and inlet headers l and 8,respectively, spaced above the bottom of the shell 2. Extending betweenthe headers! and 8 with their'opp'osite ends suitably secured intheinner side walls thereof is an assembly of parallel, horizontal waterheating pipes 8 laterally spaced, the outer pipes of the assemblybeingspaced from the shell '2 and said pipes being arranged on the underside of the assembly to form a transverse arch 9 extending throughoutthe assembly all for the purpose of facilitating the passage of heataround and through the assembly. The shell 2 is provided with a falsebottom, beneath the headers] and 8 comprising a pair of horizontalplates It extending inwardly and downwardly along the sides 3 of theshell 2 at a slight inclination and forming therebetween in thelongitudinal center of the shell 2 a narrow heat inlet H. A pair ofupwardly convergent plates I2 extending from the bars 4 tosaid' plates10 form together with the latter a burner pit I3 in the bottom of theshell 2 extending from end to end of the latter and functioning as acombustion chamber. The headers I, 8 are provided with bottom drainplugs l4 and the inlet header 8 with a pressure gage I5, a safety valve16 and a water level gage ll. At the top of the shell 2 is a. pluralityof upstanding heat discharge flues I8 spaced apart longitudinally of theshell and communicating with a heat discharge manifold pipe l9 extendingforwardly from the boiler I and presently referred to in detail. 7

The described boiler l is designed to be set up, in the preferredembodiment of the invention on the ground, represented at A, and over anunderground main water supply line 20 extending longitudinally of theboiler and prefer- The line 20 is connected at a suitable distance fromthe rear ,end of the boiler I to a Water storage tank 2| which may besunk in the ground A, or not, as desired, and to which water may be fed,under pressure, from any suitable source of supply, not

shown. The line 20 is designed'to extend for any' desired distancebeyond the front end of the boiler 2 and preferably to terminate in alateral branch of a return line 22 leading to the top of the tank 2|.Adjacent the terminal, front end, of said line 20 is a distributingassembly of laterally extending pipes 23 on opposite sides of said line20 and which are designed to be extended for any desired distancepreferably underground to remote points. The pipes 23 may extend in astraight line, or not, as desired. Spaced along said pipes 23 atsuitable intervals are distributing taps 24 laterally extending and of Tform with distributing valves 25 therein.

A valve 21 is interposed in the line 2|] imme diately in front of thedescribed distributing assembly to cut off flow through the return line22, which line may be eliminated if desired. 7

A supply branch, feed pipe 28 extends upwardly and forwardly from themain supply line at the rear of the boiler I to the upper part of therear header 8 with a cutoff" valve 23 interposed therein. A similaroutlet pipe 30 extends downwardly from the upper front part of the frontheader 1 to said line 20 with a cutoff valve 3| interposed therein.Intermediate the feed pipe 28 and the boiler is a cutoff valve 32provided in the line 20 and which, when closed, provides for bypassingthe water from the line 23 through the boiler I back to said line 23 toflow therethrough to the distributing assembly of pipe 23.

Coming now to the heater features, in the longitudinal center of the pitl3, and disposed on the ground, is a suitably supported trough 33forming a drip catching and heating pan for waste oil. Spaced slightlyabove the trough 33 and extending parallel therewith is a tubular burner34 closed at its front and rear ends. The burner 34 is supportedimmediately below the inlet II in a manner presently explained.Extending forwardly and horizontally from the front crown sheet 5 of theshell 2 is a tubular air manifold 35 for admitting atmospheric air intothe pit I3. Extending into the manifold 35 a1ong the bottom of the sameis a smaller fuel injector tube 36 projecting out of the inner end ofmanifold 35 and terminating in an ejector nozzle 31. The nozzle endofsaid tube 35 extends into and is suitably fixed in the front end.- ofthe burner 34 so as to support the same. The injector tube 36 forms partof a fuelsu-pplyline 43 leading from the compression side of a suitablefuel pump 39, the suction side of which is connected by a pipe 43 to thebottom of a fuel supply tank 4| for oil or other fuel.

Extending into the manifold 35 parallel with and spaced above theinjector tube 35 is a small fuel injector tube 42 formingpart of anairline 43 extending from an air compressor 44.- The fuel injector tube42, within the manifold 35,-is connected to the air injector tube 36 bymeans of a plurality of branches 45 extending downwardly and rearwardlytherefrom and preferably equidistantly spaced along said tubes.

The fuel pump 33-, fuel supply tank 4|, and air compressor 44, arepreferably arranged in line in front of the boiler l on the surface ofthe ground andintermediate said pump and compressor is a suitableoperating motor 46 therefor.

The burner 34 is provided at the top-thereof with a plurality oflongitudinally and equidistantly spaced upstanding burner jets 41 and atthe bottom thereof with similarly spaced small ports 48. alternatingwith said jets 4?. In advance .of the ports 48, said burner is providedwith upwardly and rearwardly inclining short baffles 4.3. Any suitabletype of electric ignition,

tions, the water from the supply tank I, under pressure, fills theheader 8 and pipes 8' and header 1. The fuel is pumped from the fuelsupply tank 4| by the pump 39 through the fuel supp y line 43. and mixedwith air from air line '38 and air injector tube 36 into the burner 34.

In its passage through the injector tube 36 said fuel ismixed with theair under compression from the compressor 44 which enters said injectortube 35 by way of the air line 33, fuel injector tube 42, and branches45. mixing of the fuel, and air, both under-pressure, causes the fuel tobe atomized as it issues out of said tube 36 and is dischargedinto theburner-34 through the plates 4|. The burnerjets 41 now being lit, thewater in the boiler is heated by way ofthe heat arising through theinlet againstthe deseri-bedassembly of water heating pipes 8'. Thehea-trising through said assembly of pipes 8 escapes from the shell 2 by wayof the discharge flues l8 intothe discharge manifold pipe 13. Preferablysaid manifold pipe |3-- is extended through the bottom of the fuelsupply tank 4| to terminate exteriorly thereof in an upstandingdischarge end i9". Thus the discharged heat and products of combustionfrom the shell 2 are utilized to heat the oil, or other fuel, insaidtank 4 t. The plates 4|-' and baiiles 49- in the burner- 34 function tobreak up the particles of oil in the burner 34 andfacilitatecombustion.- Any condensation of oilaccumulating-in the burner-34gravitatesout of the ports 48- into the trough 33 which serves to catchwaste oil. The water'inthe boiler having been heated to the requiredtemperature as shown by the gage I5, the valve is opened to permit theWater to discharge from the header 1 back into the line 25 and to flowto the pipes 23 of the distribution assembly. Obviously, by selectivelyopening val-ves25, the heated water may be discharged through thecorresponding taps 24- and the ground saturated or pools filledwithheated waterat selected locations. The return line 22 may beutilized, valves 25 being closed, andvalve 21 opened to shunt the waterfrom the. line 20 and boilerback into thegsupply tank 2| forrecirculation to said boiler.

In the modified form of'the invention shown in Figure 6, atubular burner54' is provided similar to burner 34 with the following exception.Midway ofits ends, said burner-5| is providedwith 9.

54, said burner is provided in the topthereof with a depending wedgeshaped, spreader 55 for defleeting; the fuel passing through said;plates to.- ward opposite ends of cam-burner. In; this form oftheinventiom baffles. 55;. similar to bafiies 49, are provided in: thebottomv of the burner but inclining in opposite directions upon oppositesides of the spreader 55.

In Figures 8 and 9 the plant of my invention has been shown as adaptedfor domestic heating purposes. This adaptation of the invention is thesame in all respects as the preferred embodiment already described withthe following exception. The water storage tank 51, into the top ofwhich water is admitted under pressure by way of line 58, is connectedat its bottom to the inlet header 59 of the boiler 60 by a feed line 6|having a pump 62 interposed therein and a control valve 63 in said linebetween the pump and said header. The outlet header 64 has extendedtherefrom a discharge line 65 communicating with a pair of opposedradiating coils 66 each communicating, as by return branches B1, 68 witha return line 69 leading to the top of said tank 51. In this adaptationof the invention, the water is pumped from the tank 51 to the boiler 60and into the line 65 and coils 66 to be returned to the tank 57 as willbe clear. The coils 66 and 61 may be arranged at any remote locationdesired. A suitable float valve in the tank 51 is provided for closingthe end of the line 58 when said tank is approximately full and as shownin Figure 9.

The foregoing will, it is believed, suflice to impart a clearunderstanding of my invention without further explanation.

Manifestly, the invention as described, is susceptible of modificationin other respects and as described without departing from the inventiveconcept and right is herein reserved to such other modifications as fallwithin the scope of the subjoined claim.

What I claim is:

In apparatus of the class described, a boiler comprising a pair of inletand outlet end headers of tank-like form, a water inlet pipe lineextending into the inlet header, a water discharge line extending fromthe outlet header, water circulating pipes extending between saidheaders, a combustion chamber in said boiler below said circulatingpipes, a tubular air inlet manifold extending outwardly from one end ofthe boiler and opening into said chamber, a tank for a fluid fuelsupply, a fuel supply line extending from said tank to said chamberthrough said manifold, a fuel pump in said fuel supply line, a tubularburner in said chamber attached to said line, an air compressor, acompressed air line extending from said compressor into said manifoldparallel with said fuel line and having branches connected to the latterin said manifold, a plurality of flue pipes upstanding from the top ofthe boiler for the escape of the products of combustion therefrom, and afuel heating line into which said flue pipes open and extending throughthe bottom of said tank.
